A seizure is a paroxysmal episode of symptoms or altered behavior arising from abnormal excessive or synchronous brain neuronal activity. [5] A focal onset seizure arises from a biological neural network within one cerebral hemisphere, while a generalized onset seizure arises from within the cerebral hemispheres rapidly involving both hemispheres.
Complex partial status epilepticus (CPSE) is one of the non-convulsive forms of status epilepticus, a rare form of epilepsy defined by its recurrent nature. CPSE is characterized by seizures involving long-lasting stupor, staring and unresponsiveness. [1] Sometimes this is accompanied by motor automatisms, such as eye twitching. [2]
A seizure is a sudden change in behavior, movement or consciousness due to abnormal electrical activity in the brain. [3] [6] Seizures can look different in different people.. It can be uncontrolled shaking of the whole body (tonic-clonic seizures) or a person spacing out for a few seconds (absence seizure
Generalized epilepsy is a form of epilepsy characterised by generalised seizures with no apparent cause. [1] Generalized seizures, as opposed to focal seizures, are a type of seizure that impairs consciousness and distorts the electrical activity of the whole or a larger portion of the brain (which can be seen, for example, on electroencephalography, EEG).
Thereafter, the seizure may or may not evolve into loss of consciousness and a generalized tonic–clonic seizure. [2] [1] In contrast to the auras in ecstatic seizures, most auras of seizures generally are unpleasant, including feelings of anxiety and fear (60%) as well as depression, while positive feelings are only rarely reported. [1]
Benign infantile epilepsy (BIE), also known as benign infantile seizures (BIS), is an epilepsy syndrome of which several forms have been described. The International League Against Epilepsy (ILAE) classify two main forms of the syndrome (familial and nonfamilial) [ 1 ] though several other forms have been described in the academic literature.
[91] [92] A form of an infection with the pork tapeworm (cysticercosis), in the brain, is known as neurocysticercosis, and is the cause of up to half of epilepsy cases in areas of the world where the parasite is common. [72] Epilepsy may also occur after other brain infections such as cerebral malaria, toxoplasmosis, and toxocariasis. [72]
